Complement activation in individuals with previous subclinical Lyme borreliosis and patients with previous Lyme neuroborreliosis

AbstractLyme borreliosis (LB) is caused byBorrelia burgdorferi and infection may lead to not only a large variety of clinical manifestations but also a subclinical outcome. The aim of the present study was to investigate if there is a constitutional difference in complement activation between individuals with previous subclinical Lyme borreliosis (SB) and patients previously diagnosed with Lyme neuroborreliosis (LNB).Lepirudin plasma for activation studies was collected from 60 SB individuals and from 22 patients pre-diagnosed with LNB. The plasma was incubated with liveBorrelia spirochetes of two strains (complement sensitiveB. garinii Lu59 and complement resistantB. afzelii ACA1).Complement factor C3 was measured in non-activated lepirudin plasma with immune-nephelometry and C3a and sC5b-9 generated during complement activation were measured by enzyme-linked immunosorbent assay.We found that the complement sensitive Lu59 induced higher complement activation than the complement resistant ACA1 when measuring activation products C3a and sC5b-9 in SB and LNB patients,p

AbstractObjectivesThere is a lack of data on patients ’ and diagnostic factors for prognostication of complete recovery in patients with non-idiopathic peripheral facial palsy (FP).MethodsCohort register-based study of 264 patients with non-idiopathic peripheral FP and uniform diagnostics and standardized treatment in a university hospital from 2007 to 2017 (47% female, median age: 57  years). Clinical data, facial grading, electrodiagnostics, motor function tests, non-motor function tests, and onset of prednisolone therapy were assessed for their impact on the probability of complete recovery using univariable ...

(Natural News) You probably know that Lyme disease comes from ticks, but if you don’t personally suffer from it, you’d be forgiven for not knowing much more about it. However, there is one aspect of this disease that everyone should be concerned about, and that’s the possibility that it originated as a biological weapon developed...

The objective of the study was to determine the infection prevalence of Borrelia burgdorferi, a causative agent of Lyme disease, in the province's ticks and the seroprevalence in its dogs. It was found that 97.8% (n = 368) of ticks submitted were Ixodes scapularis, a species capable of transmitting Borrelia burgdorferi; 10.3% of these ticks [95% confidence interval (CI): 3.6% to 17.0%] were infected. Provincial canine seroprevalence for the 199 submitted samples was estimated at 3.0% (95% CI: 1.0% to 5.1%). PMID: 33012828 [PubMed - in process]

CONCLUSIONS: Lyme disease is rare, but must be kept in mind when investigating the etiology of chorioretinitis and retinal vasculitis. The patient reported here is, to our knowledge, the second case reported in literature that shows atypical clinic for Lyme disease with unilateral chorioretinitis without Erythema chronicum migrans (ECM).
